BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to riot control equipment and more particularly to a net throwing device.
2. Description of Related Art
Law enforcement officers have long used less lethal weapons (e.g., batons and whips) to disperse crowds and detain rioters. Since recent decades, riot control officers have also used tear gas, pepper spray, rubber bullets, and electric tasers.
There is a typical net gun utilizing a stock, an action member, a firing chamber, a manifold, and a plurality of barrels connected to the manifold is disclosed. Each barrel is configured to receive a projectile having an inner bore that is closely fitted over the external diameter of the barrel. Each barrel has a restrictor at the manifold end. Apertures are formed through the wall of the projectile adjacent to the barrel.
While it has some utility, improvements in these products are desired, and these improvements are provided by the invention.
SUMMARY OF THE INVENTION
It is therefore one object of the invention to provide a net throwing device for use in combination with a compressed air powered launching device, comprising a pod comprising an axial space, a plurality of tubes disposed around the axial space, and a slot formed on an edge; a net disposed in the axial space; a plurality of weights each disposed in one of the tubes; and a casing comprising a forward oriented projection on an edge of a front end, the forward oriented projection being fitted in the slot to secure the casing and the pod together, and a protrusion adjacent to the forward oriented projection; wherein at least one of the tubes is inclined with respect to an axis of the axial space, and at least one of the tubes is parallel to the axis of the axial space.
The above and other objects, features and advantages of the invention will become apparent from the following detailed description taken with the accompanying drawings.

 DETAILED DESCRIPTION OF THE INVENTION
Referring to FIGS. 1 to 9B, a net throwing device in accordance with the invention comprises the following components as discussed in detail below.
A pod 1 has a circular longitudinal section and comprises an axial space 11 having a widened mouth and adapted to receive a net 4, a rear channel 12 communicating with the space 11, a plurality of tubes 13, 14, 15, 16 and 17 formed around the space 11 and each of the tubes 13-17 having a rear tunnel 18 communicating with itself, a plurality of weights 5 (e.g., weights 51, 52 and 53) each disposed in one of the tubes 13 to 17, a plurality of ropes 40 each interconnecting the weight 5 and the net 4, and a slot 19 on a circumferential edge.
Alternatively, the tunnels 18 are eliminated in another embodiment (see FIG. 4).
As shown in a first configuration (see FIG. 3), there are eight tubes in which the tubes 13, 14 and 15 are horizontal but the tubes 15 are offset at an angle from an axial axis of the channel 12, the tube 17 is inclined upward with respect to the tube 13, and the two tubes 16 are also inclined upward with respect to the tube 13 but have an inclined angle less than that of the tube 17.
As shown in a second configuration (see FIG. 6A), it is similar to the first configuration but lengths of the tubes 16 and 17 are different from that shown in the first configuration.
As shown in a third configuration (see FIG. 6A), it is similar to the first configuration in which the tube 13 is horizontal, the tubes 14 are inclined downward, the tubes 15 are horizontal and are offset at an angle from an axial axis of the channel 12, the tube 17 is inclined upward with respect to the tube 13, and the two tubes 16 are also inclined upward with respect to the tube 13 but have an inclined angle less than that of the tube 17.
As shown in a fourth configuration (see FIG. 6B), there are six tubes in which the tubes 13 and 14 are horizontal but the tubes 14 are offset at an angle from an axial axis of the channel 12, and the tubes 17 are inclined upward with respect to the tubes 13.
As shown in a fifth configuration (see FIG. 6C), there four tubes in which the tube 13 is horizontal, the tubes 15 are horizontal and are offset at an angle from an axial axis of the channel 12, and the tube 17 is inclined upward with respect to the tube 13.
As shown in a sixth configuration (see FIG. 6D), it is similar to the fifth configuration in which the tubes 13 are horizontal and the tubes 17 are inclined upward with respect to the tubes 13.
A hollow, cylindrical casing 2 comprises a forward oriented projection 21 on a front edge and adapted to fit in the slot 19, and an upward oriented protrusion 22 adjacent to the projection 21. The pod 1 is mounted in a head of the casing 2 which is in turn mounted in a launching device 5 in a ready to launch position (see FIG. 7). The launching device 5 can release compressed air to flow through the casing 2. And in turn, the compressed air flows to the channel 12 and the space 11, and flows to the tunnels 18 and the tubes 13 to 17 respectively. Finally, the compressed air projects the net 4 and the weights 5 out of the net throwing device to entangle target(s) (see FIGS. 8, 8A and 8B).
In operation, a law enforcement officer may fire the net throwing device from the shoulder (see FIG. 9). Further, the aim of the projected net 4 is the shoulder of a person (see FIG. 9A).
Alternatively, the law enforcement officer may fire the net throwing device from the lumbar region (see FIG. 9B). Further, the aim of the projected net 4 is the lumbar region of a person.
While the invention has been described in terms of preferred embodiments, those skilled in the art will recognize that the invention can be practiced with modifications within the spirit and scope of the appended claims.
